hey people, i hav a 230v ac motor taken out from a mixer(a common household kitchen mixer). the rmp of that motor is very high, so i want to wire a rheostat so that i can control its speed(rmp). I tried using a common ceiling FAN REGULATOR (i think its also a rheostat) thinking that it can hold the voltage and current (since fan runs in 230 v ). The rheostat has 1 to 5 division, in case of celling fan,level 1 makes the fan to rotate at minimum speed and level 5 lets full current to flow, hence the fan rotates at maximum speed.But when i wire the rheostat(serial connection) to my ac motor only level 5(full voltage) could power it, rest lower levels didnt power it. Hence i couldnt control the motors speed.So i need help with it. I DONT KNOW THE VOLTAGE OF MY MOTOR(if it has).CAN I USE SOME OTHER METHODS ?CANT I USED CAPACITORS OR RESISTORS WITH rheostat TO MAKE IT WORK?
Hearken to Dave, but i would wager your motor would now not run on 110v. A 5 hp motor on a 110v can be pulling over 30 amps. Then you're going to have a further problem. Your 110v circuit that you would plug the motor into would normally go back and forth, because 110v circuits are 20 amp or 15 amp breakers simplest. The wires in the 110v circuit is not going to be competent to manage the warmness. If your motor IS a dual voltage motor, it could be 230v/460v. That will make sense. At 460v, your motor would pull about eight amps most effective.
A motor taken out of a kitchen mixer is almost certainly a universal motor. A universal motor should work well with a rheostat, but you probably need a lower resistance value than would be used with a ceiling fan motor. The fan regulator that you have may be an electronic voltage regulator rather than a rheostat.
